Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery for safety.

2. Lift the Vehicle

Use a jack to lift the rear of the vehicle.
Secure with jack stands to ensure safety while working.

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the rear wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Inspect Pads:
- Remove the caliper bolts with a socket wrench.
- Carefully slide the caliper off the brake pads without disconnecting the brake line.
- Check the thickness of the brake pads; replace if below manufacturer specifications.
Replace Pads:
- If replacement is necessary, remove the old pads from the caliper bracket.
- Install new brake pads, ensuring they are seated correctly.
- Apply brake grease to the back of the pads to reduce noise.

5. Inspect and Resurface or Replace Rotors

Check the rotor surface for scoring or warping.
If damaged, either resurface the rotors using a brake lathe or replace them with new rotors.
Ensure the rotor surface is clean and free of debris.

6. Reassemble Components

Reattach the caliper over the new brake pads.
Tighten the caliper bolts to the manufacturer's torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully remove jack stands and lower the vehicle using the jack.
Tighten the lug nuts to the correct torque specification while the vehicle is on the ground.
